Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to a license plate mounting structure in an automobile.

(Prior Art) Conventionally, for example, the mounting structure of the license plate is shown in FIGS. 3 and 4.

FIG. 3 shows the first conventional example.

According to this, reference numeral 1 denotes a rear panel forming a rear surface of the vehicle body which is a stationary side of the vehicle body. The upper and lower middle portions of the rear panel 1 bulge rearward, and the resin bumper 3 is joined to the outer surface of the bulging portion 2. Has been done. Further, the license plate 4 is superposed on the surface of the bumper 3 so that the bumper 3
And the upper part of the license plate 4 by the bolt 5,
It is fastened together with the bulging portion 2.

In the case of the above configuration, the lower end of the license plate 4 is a free end. Therefore, if left as it is, the lower end of the license plate 4 may flutter during traveling.
Therefore, when the protrusion 7 is formed on the lower surface of the bumper 3 and the license plate 4 is fastened, the lower end of the license plate 4 is pressed against the protrusion 7 so that the license plate 4 is elastically bent slightly. I am doing it. And thereby, the license plate 4
It prevents fluttering at the lower end of the.

Further, with the above configuration, a gap 8 is formed between the lower end of the bumper 3 and the lower end of the license plate 4. Then, the license plate 4 may be easily bent due to mischief utilizing the gap 8. Therefore, in order to prevent this, the above-mentioned gap 8
A cover piece 9 for covering is formed integrally with the lower edge of the bumper 3.

On the other hand, FIG. 4 shows the second prior art.

According to this, the bulging portion 2 slightly above the bolt 5
A bead 10 protruding outward is formed on the swelling portion 2 so that the bumper 3 is pressed against the bead 10.
Has been concluded. The deformation of the bumper 3 and the license plate 4 above the bolt 5 at this time causes the bolt 5 to bring the lower side of the license plate 4 into close contact with the outer surface of the bumper 3. That is, this prevents the lower end of the license plate 4 from fluttering or being easily bent.

(Problems to be Solved by the Invention) Incidentally, according to the first conventional example, the structure of the mounting structure of the license plate 4 is complicated because the cover piece 9 is required to be provided. Further, when the license plate 4'having a short dimension l is attached to the bumper 3 instead of the license plate 4 having a long vertical dimension L, the protrusion 7 is exposed, which means that the mounting portion of the license plate 4 is attached. This is not preferable because it causes the deterioration of the appearance quality.

On the other hand, according to the second conventional example, local surface strain is likely to occur in the portion of the bumper 3 corresponding to the bead 10, and the lower end position of the bumper 3 is likely to be uneven in the front and rear in each portion in the vehicle width direction. . Therefore, even with this configuration, there is a problem that the appearance quality is deteriorated.

(Purpose of the Invention) The present invention was made by paying attention to the above situation, and when the license plate is mounted on the stationary side of the vehicle body without fluttering, the mounting is easy. It is possible to achieve such a structure by using such a different structure, and to maintain good appearance quality at the mounting portion of the license plate.

(Structure of the Invention) A feature of the present invention for achieving the above-mentioned object is that a fastening seat surface formed on the back surface of the bumper is fastened when fastening the bumper to the stationary side of the vehicle body and the upper portion of the license plate. , The outer surface on the stationary side of the vehicle body facing this is inclined so that it gradually separates as it goes downward, and a rib is projected on the back surface of this bumper below the fastening part of the bumper to the stationary side of the vehicle body. It is at the point where the protruding end is brought into contact with the outer surface on the stationary side of the vehicle body.

(Operation) The operation of the above configuration is as follows.

The bumper 3 and the upper portion of the license plate 4 which is superposed on the surface of the bumper 3 are rear panels (on the stationary side of the vehicle body).
In the case of tightening together with 1, the fastening seat surface 13 formed on the back surface of the bumper 3 is inclined so as to gradually separate from the outer surface of the rear panel 1 which faces the fastening seat surface 13, so that the above fastening is performed. Then, when the fastening seating surface 13 is pressed against the outer surface of the rear panel 1 facing the fastening seating surface 13, a part F of the fastening force at the time of fastening is more than the fastening portion of the bumper 3 to the rear panel 1. The lower bumper 3 and the license plate 4 are pushed toward the rear panel 1.

By the way, a rib 16 is projectingly provided on the back surface of the bumper 3 below the fastening portion, and the projecting end of the rib 16 is in contact with the outer surface of the rear panel 1. Therefore, the bumper 3
The pushing of the lower end of the license plate 4 toward the rear panel 1 is restricted by the rib 16 contacting the rear panel 1.

Therefore, a part F of the fastening force is applied to the license plate 4 while elastically deforming the bumper 3 around the fastening seat surface 13.
The lower end of the bumper 3 is brought into close contact with the surface of the bumper 3.

Further, as described above, since the fastening seat surface 13 is formed on the back surface of the bumper 3, the vertical dimension L with respect to the bumper 3 is L.
The fastening seating surface 13 is not exposed regardless of whether or not the long license plate 4 is replaced with the short license plate 4 '.

Moreover, the fastening seating surface 13 has a relatively large area in order to maintain the strength for fastening. For this reason, the surroundings of the fastening seat surface 13 at the time of fastening described above are elastically deformed as a whole.

Further, the bumper 3 below the fastening portion is positioned by the rib 16 contacting the outer surface of the rear panel 1 as described above.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

The basic structure of this embodiment is the same as that of the conventional example. Therefore, for the common configuration, the reference numerals are attached to the drawings, the description thereof is omitted, and only different configurations will be described.

In the figure, a plurality of bosses 12 in the vehicle width direction are provided on the rear surface of the bumper 3.
Are formed integrally with each other, and each boss 12 has a substantially cylindrical shape, and its inner hole is a hole through which the bolt 5 is inserted. The protruding end surface of the boss 12 is the bumper 3
Is a fastening seat surface 13 for fastening the rear panel 1 to the rear panel 1.

As shown by the solid lines in FIGS. 1 and 2, before the bumper 3 and the license plate 4 are fastened to the rear panel 1, the fastening seat surface 13 faces the outer surface of the bulging portion 2 facing the fastening seat surface 13. It is inclined to gradually separate as it goes downward.

The base portion of the boss 12 is a thin portion 14, that is, has a shape that is easily elastically deformed. A nut 15 for screwing the bolt 5 is welded to the inner surface of the bulging portion 2 corresponding to the boss 12.

The bolt 5 corresponds to a fastening portion of the bumper 3 to the rear panel 1, and a rib 16 is provided on the back surface of the bumper 3 below the bolt 5 so that the rib 16 extends along the vehicle width direction. ing. Each portion of the protruding end of the rib 16 in the vehicle width direction is in contact with the outer surface of the rear panel 1.

In addition, a vertical rib 17 that intersects the rib 16 in the vertical direction.
However, the bumper 3 is integrally projectingly provided on the back surface of the bumper 3, and the rigidity of the bumper 3 below the bolt 5 is sufficiently enhanced.

When fastening the bumper 3 and the upper portion of the license plate 4 to the rear panel 1, first, the bolt 5
Screw into nut 15. When this fastening progresses and the fastening seating surface 13 is pressed against the outer surface of the bulging portion 2 facing the fastening seating surface 13 so as to come into surface contact with the fastening seating surface 13, as shown by the arrow in FIG. Part F of the above will push and move the bumper 3 and the license plate 4 below the bolt 5 toward the rear panel 1.

However, at this time, since the rib 16 is in contact with the rear panel 1, it is restricted that the bumper 3 and the license plate 4 are pushed and moved toward the rear panel 1. Therefore, as shown by a phantom line in FIG. And part of the fastening force F
While the elastically deforming the thin portion 14 around the fastening seat surface 13, the lower end side of the license plate 4 is brought into close contact with the surface of the bumper 3.

The fastening seat surface 13 has a sufficient area to withstand the fastening force of the bolt 5 in terms of strength.

Further, instead of the long license plate 4 having a vertical dimension L shown by a solid line, a license plate 4'having a short dimension 1 can be attached to the bumper 3.

Although the above is based on the illustrated example, the boss 12 may have a short transverse cross section, and the boss 12 may be elongated in the vehicle width direction. Further, the thin portion 14 may be omitted. Furthermore,
A plurality of ribs 16 may be provided as members short in the vehicle width direction.

(Effect of the Invention) According to the present invention, when the bumper and the upper portion of the license plate that is superposed on the surface of the bumper are fastened together to the stationary side of the vehicle body, the fastening seat formed on the back surface of the bumper. Since the surface is inclined so as to gradually separate from the outer surface of the vehicle body stationary side facing it, as it goes downward, the fastening progresses and the fastening seat surface makes surface contact with the outer surface of the vehicle body stationary side facing this. When pressed against, the part of the fastening force at the time of fastening pushes the bumper and the license plate below the fastening portion toward the stationary side of the vehicle body.

Further, in this invention, a rib is provided on the back surface of the bumper below the fastening portion, and the protruding end of the rib is in contact with the outer surface on the stationary side of the vehicle body. The pushing of the lower end toward the stationary side of the vehicle body is restricted by the rib contacting the stationary side of the vehicle body.

Therefore, a part of the fastening force causes the lower end side of the license plate to come into close contact with the surface of the bumper while elastically deforming the bumper around the fastening seat surface. Therefore, it is possible to prevent the lower end of the license plate from fluttering or easily bend the license plate.

Since the above-described effect is obtained by simply inclining the fastening seat surface formed on the back surface of the bumper with respect to the stationary side of the vehicle body, the installation of the license plate can be achieved with a simple configuration.

However, since the fastening seat surface is formed on the back surface of the bumper as described above, regardless of whether or not the license plate of short dimension is attached to the bumper, instead of the license plate of long vertical dimension. However, the fastening seat surface is not exposed.

Moreover, the fastening seat surface has a large area to some extent in order to maintain the strength for fastening.
Around the fastening seating surface at the time of fastening as described above, elastic deformation is performed gently as a whole. Therefore, this deformation is prevented from appearing as a local surface strain as in the conventional case.

Further, since the bumper below the fastening portion is positioned by the rib contacting the outer surface on the stationary side of the vehicle body as described above, even if the bumper is elastically deformed by the fastening, the lower end of the bumper is lowered. It is possible to prevent the positions from being non-uniform in the front and rear in each portion in the vehicle width direction.

Therefore, the appearance quality of the mounting portion of the license plate is kept good.
